Sporting the same compact design, the successor comes with both standard-type earbuds, and swimming earbuds that help to increase water resistance, so you'll get to listen to music more comfortably while underwater. On a full charge of 90 minutes, the NWZ-W270S player is capable of delivering up to eight hours of audio playback. Its quick-charge function (just 3 minutes) offers music playback for up to 60 minutes, even if the battery was fully depleted.
